The Tactical Innovations M22/50 Muzzle Brake is precision
machined from heat treated 7075 aircraft aluminum
not 6061) and mil-spec type 2 hard anodized for maximum
lightweight strength and durability. It completely
eliminates any flash and directs muzzle gasses away from
the shooter and at angles away from the target.

The M22/50 Muzzle Brake is threaded 1/2-28 TPI and will thread
onto any .22LR barrel that is correctly threaded. A crush washer
(not supplied) is recommended so that you can set the position
of the muzzle brake based on the thread timing.
